Positioning and clamping mechanism of welding fixture of automobile stamping piece

Abstract

The invention discloses a positioning and clamping mechanism of a welding fixture of an automobile stamping piece, which comprises an installing seat which is installed on a bottom board of the welding fixture; one end of the installing seat is provided with a locking cylinder, and the other end of the installing seat is fixed with a supporting block; a piston rod of the locking cylinder penetrates through the installing seat and the supporting block; a positioning pin which is positioned towards a positioning hole of the stamping piece is fixed on the extending end of the piston rod of the locking cylinder; the upper end of the installing seat is hinged with a bent pressing block; the lower end of the pressing block is buckled outside the supporting block; and a hinge mechanism is also fixed on the piston rod of the locking cylinder and is hinged with the upper end of the bent pressing block through a connecting rod. According to the invention, one locking cylinder is adopted for simultaneously realizing positioning and clamping functions; the manufacturing cost of the fixture is reduced; and an enough space for operation is reserved for a welding gun, so as to be convenient for operation of workers and favorable for enhancing production efficiency.

Description

technical field [0001] The invention relates to a positioning and clamping device, mainly a positioning and clamping mechanism for a welding jig of an automobile stamping part. [0002] Background technique [0003] At present, in the automobile manufacturing industry, in order to ensure that the welding products of stamping parts are qualified, reduce the labor intensity of workers and improve the production efficiency of the factory, pneumatic welding fixtures have been widely used. However, in these welding fixtures, the separation of the positioning mechanism and the clamping mechanism is generally used, which makes the fixture structure relatively complicated and increases the manufacturing cost of the fixture; at the same time, the complicated fixture structure also makes the welding torch operating space small and inconvenient for workers to operate; positioning The separation of the clamping structure also reduces the operating efficiency and limits the improvement o...
